When i open a text file with notepad++ all the spaces between "word" and "//" are messed up, but that doesn't happen if i open the same file with any other notepad, why this is happening and how can i fix it? Sorry for my english
that's what happens when you mix spaces and tabs. Try clicking View / Show symbol / Show Whitespace and TAB. Now you have two options:
a) convert all spaces to tabs (or vice versa)
b) see how long is TAB supposed to be (2, 4 or 8 spaces) and set that value in Preferences / Tab settings / Tab size
Option b) means you don't need to edit the file.
